Types of joints, Biology

1.      FIBROUS OR IMMOVABLE JOINTS -

Occur between the bones of cranium & in the tooth suckets commonly in the form of sutures.

2.      CARTILAGINOUR OR SLIGHTLY MOVABLE JOINTS -

Often called symphysis. Occur between vertebrae, at pubic symphysis and between ribs & sternum.

3.      SYNOVIAL OR FREELY MOVABLE JOINTS -

Free movable joitns permit a great deal of movment.

At a synovial joint the adjacent bones are often so straped that, an enlargement of the one fits intodepression in the other.

A layer of hyaline cartilage, called articular cartilage covers the ends of the bones.

A space called the synovial cavity between 2 bones present.

Cavity is lined by fibrous synovial membrane containing secretory cells.

It secrets a thick, sticky fluid.

This fluid lubricate the joints to allow nearly friction less movement of bones on each other & also nourish the joints.

Within a synovial joint are small membrane bound packets, called bursae, that stores synovial fluid.

If fluid is secreted less, the joints become inflammeted & pariful. this condition is known as osteoarthritis.
